Installation "below head" (Fig 9B): if there are no check valves between the water deposit and the system (or if they are open), it loads
automatically as soon as it is allowed to let out the trapped air. So slackening the filling cap enough to vent the trapped air (2.5 turns) allows the
system to load completely.
Tighten the cap again when the operation is complete.
Dry up any water residue in the technical compartment.

5.2 Maximum pressure at intake (pump below head)

It is important that the intake pressure is always lower than the maximum working pressure allowed by the pump as indicated in the table.

5.3 Systems in booster mode

Each pump, depending on the model, is characterised by a maximum achievable Setpoint pressure (without the suction being pressurised).
The user is allowed to set any setpoint pressure (SP) from 1.0 bar up to the maximum pressure PN, thus reaching pressure values higher than
the maximum pressure that can be achieved by the pump in order to allow use in booster mode.
Operation is as follows:
If the set pressure SP is lower than the maximum pressure achievable by the pump, the system will adjust to the set pressure;
If, on the other hand, the set pressure is greater than that achievable by the pump, the set point will be reached only if there is
pressure at intake.
Based on the setpoint set and the pressure read at intake, the pump understands whether it will achieve the desired setpoint.
If the setpoint set cannot be reached due to the reduced intake pressure, the pump will still continue to deliver water at the pressure it is able to
achieve and will show the flashing pressure gauge symbol on the main page.
